Introduction
FCC Registration
Innkeeper multi line digital hybrids will allow you to send and
receive audio over analog telephone lines. While this may
seem like a simple task that any telephone can do, the challenge is getting the best quality audio from such a limited audio
path.
What is a Digital Hybrid?
A digital hybrid connects audio signals to a standard analog
telephone line without the variations in quality found with analog hybrids. The main function of a hybrid is to bring in the callers voice from the phone line, as clear and clean as possible. In
the real world, when you send your voice down the telephone
line it has a tendency to bleed over into the caller’s audio. The
hybrid must adapt to the phone line in order to properly separate transmit and receive audio. We use a 16 bit DSP to continuously monitor the phone line and audio signals to deliver
excellent separation. Our dual-convergence algorithm can
achieve excellent trans-hybrid loss, typically exceeding 50 dB,
without any setup.
Ready to go?
The innkeeper 2/4 features diagrams will help you pinpoint any
minor questions that you may have. If this is your first exposure
to a hybrid, we suggest that you read the entire manual to allow
you to take advantage of all these features.
Any Questions?
Before you pick up the phone... Please thumb through the rest
of this manual. You might find those deep technical questions
are covered on later pages.

b) The telephone equipment's FCC registration number.
This can be found on the bottom of your telephone
equipment, and
c) the ringer equivalence number (REN) for this equipment.
The REN is used to determine the quantity of devices which
will be connected to the telephone line. Excessive RENs on
the telephone line may result in the devices not ringing in
response to an incoming call. In most, but not all areas, the
sum of the RENs should not exceed 5.0. To be certain of the
number of devices that may be connected to the line, as
determined by the total RENs, contact the local telephone
company.
3. Repair Instructions
If it is determined that your telephone equipment is
malfunctioning, the FCC requires that it not be used and
that it be unplugged from the modular outlet until the
problem has been corrected. Repairs to this telephone
equipment can only be made by the manufacturer or its
authorized agents or by others who may be authorized by
the FCC. For repair procedures, follow the instructions
outlined under the warranty section of the manual.
4. Rights of the telephone company
If telephone equipment is causing harm to the network, the
telephone company may temporarily discontinue your
telephone service. If possible, they'll notify you before they
interrupt service. If advanced notice isn't practical, you'll be
notified as soon as possible. You'll be given the opportunity
to correct the problem, and you'll be informed of your right
to file a complaint with the FCC.
Your telephone company may make changes in its
facilities, equipment, operations or procedures that could
affect the proper functioning of your JK Audio product. If
such changes are planned, you'll be notified by your
telephone company.

• RJ-45 Ethernet port
• RS-232 remote control port with simple ASCII protocol
• No external power required
• Indication of incoming ring per line
• On-Hook and Off-Hook
• Place call on hold or release hold
• Dial (number) (line)
• Auto-Answer on/off, set ring count
• Test tone start / stop per line
• Automatic Gain Control on/off
• Audio level - Send and Receive
• Master Send on/off
• Phone Book updates

Turn only these
two knobs all the
way down so
this audio does
not go back to
the same caller.
Turn all other
knobs up so
each caller can
hear all mics and
other callers
For whichever input channel you have each Caller connected to, turn the
corresponding Aux control to minimum (usually hard left) so each Caller will
not hear their own audio. Each Aux Send bus is completely separate from
all other outputs, so each row of Aux controls will not affect what is heard
on the Main outputs or on other Aux buses. If possible, the Aux Send buses
should be pre-fader, so you can use the fader controls to set the levels of
each channel to the main output without affecting the audio sent to the
Caller through the Aux Send buses. The innkeeper 2 was used in this example. Follow the same strategy for an innkeeper 4 with 4 Aux Send buses.

Connecting Cables
Although each application will require a slightly different setup, the
following is a general cable connection setup and explanation. Using
balanced XLR cables (not included) with 1/4” TRS adapters if necessary for your mixer, make all connections as shown.
Advanced Conference Options Signal Flow Diagrams
• Phone Line - Connect the supplied RJ-11 phone line cable(s) be-
tween the RJ-11 jack(s) marked "Line" and your wall jack(s). Be
sure these jacks can support standard analog telephone operation. The innkeeper 2/4 will not work with "dry pair" phone line connections.
• Send XLR - Connect a line level (mix-minus) audio signal to the
Send jack(s) on the innkeeper 2/4. Audio will be sent down only
the corresponding phone line.
• Master Send XLR - Connect a line level (mix-minus) audio signal
to the Master Send input. Audio will be sent down either or both
phone lines based upon your menu selections.
• Caller XLR - Connect Caller output(s) to line level input(s) on your
audio equipment. Each caller output jack will contain audio only
from its corresponding phone line. Local audio and audio from alternate phone lines will not be present on these jacks. Innkeeper 2
can send isolated caller audio, mixed caller audio, or mixed caller
and local audio from the Caller XLR based on selections made in
the Conferencing menu.
• Power - Connect the supplied power cable to a 110 - 220 VAC
power outlet.
Auxiliary Telephone(s)
You can use an auxiliary telephone to place or screen a call. When
you are ready to take the call on innkeeper 2/4, press the Call button
for the corresponding phone line. That line will now pass through the
digital hybrid. If your telephone has a “Hold” feature, you can answer
the phone and place the call on hold. When you press the “Call” button, the innkeeper will automatically release the hold and connect
that line through the hybrid. If you need to take the call back on the
auxiliary telephone, simply pick up the phone before the innkeeper
2/4 Drop button is pressed for that line.

Operation - Conference (innkeeper 2 only)
Operation (continued)
Conference
One press of the conference button will join the audio paths of both
line one and line two, provided there are calls present on both lines.
Transmit Signals
The bi-color Transmit LED for each line displays the signal level as it
goes out over the phone line. The LED will display transmit signal
levels at -20 dB as green and indicate clipping at -3 dB as red. The
goal is to drive the phone line at high enough levels to avoid phone
line noise, but not so loud as to cause excessive clipping. Adjust your
Send audio signals to a level slightly less than the point where you
see occasional flashes of red on the Transmit LED. These flashes
should occur during loud speech bursts only. If the Transmit LED
stays lit red for extended periods, you can assume that much of your
speech is being clipped or distorted. In this case you should lower the
audio levels for the signal that is causing the clipping. The innkeeper
2/4 menu will also allow you to adjust your input levels in 1 dB increments over a ±10 dB range.
A second press of the conference button will break the audio paths
between the calls. An auto-dropped or manually dropped line will
automatically break the conference.
By default, line1 send and line send audio will be mixed together
digitally and sent into both phone lines. Line 1 caller will hear line 2
caller audio. Line 2 caller will also hear line 1 caller audio. In the
menu, this configuration is referred to as Send-Mix, Caller-No Mix.
This default configuration is by far the most widely used. Advanced
options are available for Conference mode; however for most situations it will not be necessary to change these default options.
Innkeeper 2 Advanced Conference Options
The factory default conference mode provides both callers with a mix
of Line 1 Send and Line 2 Send audio. Additional mix options can be
found in the Configuration menu. These options allow you to enable
and disable Send and Caller mix features. Keep in mind that no matter what options are selected, both callers will always be able to communicate with each other in Conference mode.

Line 1 Caller XLR contains Caller 1 + Caller 2 + Send 2
Line 2 Caller XLR contains Caller 1 + Caller 2 + Send 1
14
Receive Signals
The bi-color Receive LED displays the signal coming from the phone
line and out of the DSP. The LED will display receive signal levels at
-20 dB as green up to -3 dB where it will change to red. The innkeeper 2/4 menu will allow you to adjust individual Caller output levels in 1 dB increments over a ±10 dB range to give you the best signal level at your equipment. The Caller level control in the menu will
not change what you see on the Receive LED.
Auto-Answer
The Auto-Answer feature can be activated through the innkeeper 2/4
menu. You may select which phone lines will have auto-answer enabled as well as how many rings before auto-answer. When AutoAnswer is enabled, you can still take calls manually using the call
button. When finished, you can either drop the call manually or allow
the call to auto-disconnect. Innkeeper 2/4 will look for a CPC disconnect signal or ROH message from the phone company to determine
when a call has disconnected. This can take up to a minute.
Remote Jack
The 10 pin RJ-50 jack on the back of the innkeeper 2/4 provides a
proprietary connection to the supplied remote terminal block (see
page 8), using the supplied 1 meter cable. This jack can also be used
to connect to the optional JK Audio RIU-IP remote interface unit (see
page 16).

This terminal block was designed to allow remote off-hook/on-hook
control and status for each phone line. The innkeeper 2 model also
provides on/off control and status for the Conference feature. Use
only the included RJ-50 cable to connect the Remote Terminal Block
to the Remote jack on the innkeeper 2/4.
The OH Status pin will provide 5V, 50mA when the corresponding
line is off-hook. You can use this to drive a relay, light an LED, etc.
NOTE: Installation of jumper J5 will set “static” OH line control, so that a steady ground
on any control input will take the corresponding line off-hook, otherwise the line will remain on-hook. Removal of jumper J5 will return OH line control to its original “momentary”
control mode, so that any line control input that is momentarily brought to ground (for a
min. of 100ms), will toggle/switch the corresponding line state between on-hook or offhook as determined by the given line’s previous state.
